Embolization – A technique performed by a neuroradiologist or a neurosurgeon in the treatment of brain aneurysms or brain AVMs. As an extension of an angiogram, a catheter is passed up into the arteries inside the brain into the arteries supplying blood flow to the AVM or inside an aneurysm. The blood vessel or aneurysm is then blocked off from the inside with either glue, metal coils or other substances. This is often performed as a prelude to surgery in brain AVMs, but occasionally may be curative without additional therapy.
Endovascular – Within the vascular system.
Endovascular Embolization – A generic term for treatment of an aneurysm or vascular malformation from inside the blood vessel. Aneurysm coiling and AVM embolization are examples of endovascular procedures. This method uses the natural access to the brain through the bloodstream via arteries to diagnosis and treat cerebral aneurysms.
